Fire Lord Zuko has ruled over the Fire Nation for quite some time now. He's shown up to every meeting, attended every counsel and looked after his Nation. But one day, he comes down with something, and he's forced to let his advisors look after the Nation for him.
Zuko has never left the Fire Nation to his advisors, not since he took on the throne. Now he's being forced to sit back and let them make decisions for him while he recovers.
After not talking for almost a year since their second break-up, Mai is informed of Zuko's condition and offers to look after him. She never really stopped loving him, and seeing how much he has grown to care about the Fire Nation has made her fall for him even more.
However, when Zuko wakes next to Mai, Mai realises isn't sure she's got what it takes to deal with an anxious, very ill Zuko, but she loves him enough to help him in whatever way she can. Whether that be holding his hand while he panics, or holding his hair back while he pukes.
